In a certain university, the number of students who participated in the yearly fundraising activity from 2011 to 2018 can be modeled by A(x) = 3x2 - 52x + 255, where x = 1 represents the year 2011. From 2018 to 2022, the number of students is represented by A(x) = 42x - 305. Graph y = A(x) for the years 2011 to 2022 and determine the year in which the number of students who participated is the least.
